The family-centered early intervention practice emphasizes that the family are as im-portant as the children with developmental delay when they receive the service, and the approach often adopts a professional team-based model. However, such practices may have difficulties in implementing in hospitals in Taiwan due to the traditional concept of “expert guidance” existing in most medical systems. The aim of this research attempted to build a professional team-based model and investigated the effects of family-centered services. There were nine families recruited in this study after trained by the professional team members on family-centered services courses which tried to build collaborative relationships with fami-lies, and coach families how to create learning opportunities for their children in daily ac-tivities. Instruments of MPOC-SP, MPOC, FOS-RT, CDIIT-DT and GAS were used to evaluate the effects of the team-based and family-centered services after six months inter-vention. The result found significant improvements in the quality of family-centered services provided by the professional team-based model. Another significant result was found in family outcomes, such as understanding rights, helping children learn and creating a support system for their own family. The outcomes of the children also showed significant im-provements in GAS. The study suggests the professional team-based model to provide fam-ily-centered early intervention services could be effective through collaboration for en-hancing functions of family and promoting development of children with special needs.
